ARGAND LAM P.

SPECIFICATION forming part of Letters Patent No. 514,158, dated February6, 1894.

Application led June 30, 1893.

To all whom it may concern:

Be it known that I, EDWARD MILLER, Jr., a cltlzen of the United States,residing at Meriden, New Haven county, Connecticut, have invented a newand useful Improvement in Argand Lamps, of which the following is aspecification.

My invention relates to that class of Argand lamps in which a Wickadjusting sleeve surrounds the inner Wick tube.' It is intended to.provide a simple means of making such wick sleeves removable from thelamp.

In the accompanying drawings, which represent in perspective and partlybroken away so much of an Argand lamp as is necessary to show myinvention, Figures 1 and 2 show dierent forms of my device. Fig. 3 showsin detail parts shown in Fig. 2.

The same letters refer to like parts in the several views.

A, designatesafount top; o, a central opening in the top A; d', a secondopening in the top A; B, an inner wick tube; C, a wick sleeve; o, abearing on the sleeve C; D, an offset; cl, Fig. l, a socket; d,fZ,Figs.2 and 3, recesses in the offsetD; E, a drawbar; e, Fig. 1, a screwthreadat the lower end of the drawbar E; e', Figs. 2 and 3, a forked recessalso in the drawbar E.

In the example of my invention shown in Fig. l of the drawings, thefount top A, openings a and a', wick tube B and sleeve C may be of usualor convenient form. As shown, the tube B has the double function ofcentral air supply and inner Wick tube, the sleeve C is of a diameter tomove freely thereon and is adapted to carry the wick on its outersurface. These details are non-essential to my invention. The sleeve Cis provided with a vertical, tubular bearing c, in which a vertical armof an offset D is capable of limited rotation. At the outer end of thehorizontal arm of the offsetD is formed a socket d here shown asinternallyscrew-threaded. Through the opening a in the fount top Apasses a drawbar E, the lower end of which is formed with an externalscrew-thread e adapted to engage with the socket d.

The operation of my device will be readily 5o understood from anexamination of the drawf ings.

Serial No. 479|31'7. (No model.)

The oset D being rotated in the bearing c to a position tangential tothe sleeve C, the sleeve and offset may be introduced through theopening a in the fount top A, the sleeve of course surrounding the tubeB. This is shown in dot-ted lines, Fig. l. The offset D is Ithen turnedoutward radially from the sleeve C, the draw-bar E inserted through theopening a', and its lower end c screwed into the socket d. A Wick maythen be slipped on 6o the sleeve C and the lamp is ready for use. It isclear that by a reversal of the above described operation the sleeve anddraw-bar may be removed from the lamp as desired.

In Fig. 2 of the drawings I have shown the 65 offset D as formed withrecesses d', cl, adapted to engagement in the recess e at the lower endof the drawbar E. This device is most clearly shown in Fig. 3 of thedrawings. The operation of the device is not changed by 7o thesealterations, which are exhibited in proof of the fact that my inventiondoes not depend upon a particular form of embodiment. I have also shownthe opening a as provided with an internally projecting sleeve which 7 5forms a guide for the draw-bar E. When this mode of construction isfollowed, there is no obstruction Whatever to the operations of huntingand otherwise finishing thefount, the sleeve and draw-barbeingseparately finished 8o and inserted after the parts are complete.

I am of course familiar with several devices in which a draw-bar isformed with atongue adapted to detachable engagement with a socket onthe wick sleeve. By this means the removability of the sleeve isprovided for but the draw-bar cannot be released from the lamp.

I am not aware of any previous device in which an oset is pivoted to theWick sleeve 9o and provided at its free end with means for attaching itto a draw-bar. Neither am I aware of any previous device in which anoffset is pivotally secured to the wick sleeve so as to be capable ofrotation thereon in a horizontal plane. In my device the offset beingthus secured to the sleeve may be turned to such a position as to becapable of insertion with the sleeve through the collar or centralopening of the lamp While when turned to its Ioo radial position it iscapable of engagement with a straight vertically adjustable drawbar. Inthis Way the separate removability of the sleeve and draw-bar issecured.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is as follows:

l. In an Argand lamp in combination, a wick adjusting sleeve, an osetpivotally secured to said sleeve so as to be capable of limited rotationin a horizontal plane and a draw-bar, said offset and said draw-barbeing provided with means for detachably securing the one to the other,substantially as described.

2. In an Argand lamp in combination, a Wick adjusting sleeve, an oisetpivotally secured to said sleeve so as to be capable of limited rotationin a horizontal plane and a draw-bar, said offset and said drawbar beingprovided the one with a socket and the other with a portion adapted toenter said socket and to be detachably secured therein, substantially asdescribed.

3. In an Argand lamp in combination, a Wick adjusting sleeve, an oiifsetpivotally secured to said sleeve so as to be capable of limited rotationin a horizontal plane and provided with a socket and a drawbar providedat its lower end with a portion adapted to detachable engagement in saidsocket, substantially as described.

4. In an Argand lamp in combination,awick adjusting sleeve, a verticalbearing on said sleeve, an oset secured within said bearing so as to becapable of limited rotation therein and a drawbar, said offset and saiddrawbar being provided with means for detachably securing the one to theother, substantially as described.

5. In an Argand lamp in combination, a fount top, a central opening insaid fount top, a second and separate opening in said fount top, a wickadjusting sleeve, an offset pivotally attached to said sleeve, so as tobe capable of limited rotation in a'horizontal plane said sleeve andoffset being capable of passing through said central opening, and adrawbar adapted to pass through said second opening and to engage With saidoiset Within the lamp, substantially as described.
